Canon 5D MII vs Canon 7D Comparison Overview

In this review, we will be comparing 5D MII and 7D, two Advanced DSLR cameras by Canon. Canon 5D MII was introduced to market in February 2009 and Canon 7D was launched in November 2009. There is only 9 months difference between 5D MII and 7D so we are expecting this to be a fair comparison regarding age and technology level.

Here is a brief look at the main features of Canon 5D MII and Canon 7D before getting into our more detailed comparison.

Canon 5D MII vs Canon 7D: Physical Specs and Body features Comparison

Size and weight is a big decision factor when you are trying to find the ideal camera for your needs. In this section, We are going to illustrate Canon 5D MII and Canon 7D side-by-side from the front, back and top in their relative dimensions. Canon 5D MII has external dimensions of 152 x 114 x 75 mm [5.98 x 4.49 x 2.95″] and weighs 850 g [1.87 lb / 29.98 oz] [including batteries]. Canon 7D has external dimensions of 148 x 111 x 74 mm [5.83 x 4.37 x 2.91″] and weighs 860 g [1.90 lb / 30.34 oz] [including batteries].

Below you can see the front view size comparison of Canon 5D MII and Canon 7D. Canon 7D is clearly the smaller of the two cameras. Its body is 4mm narrower, 3mm shorter and 1mm thinner than Canon 5D MII.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Canon 5D MII is 10g lighter than the Canon 7D but we don't think this will make a significant difference.

Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Canon 5D MII has a Full frame sensor and Canon 7D has a smaller APS-C sensor, Canon 7D's lenses for a similar focal length and aperture will generally be lighter and smaller than the Canon 5D MII lenses.

Weather Sealing

Both 5D MII and 7D have weather sealings in their body, making them resistant to water and dust.

Canon 5D MII and Canon 7D's LCD screens has the same diagonal size of 3.00".

Canon 5D MII vs Canon 7D: Sensor Comparison

Canon 5D MII has a 21.0MP Full frame [36 x 24 mm ] sized CMOS sensor and features Digic 4 processor. On the other hand, Canon 7D has a 18.0MP APS-C [22.3 x 14.9 mm ] sized CMOS sensor and features Dual Digic 4 processor.

Below you can see the 5D MII and 7D sensor size comparison.

As seen above, Canon 5D MII has a 2.6x Larger sensor area than Canon 7D. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.

Both Canon 5D MII and Canon 7D sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth [DXO Portrait], dynamic range [DXO Landscape] and low-light sensitivity [DXO Sports], and also gives them an overall score. Of the two cameras that we are comparing, 5D MII has scored 79, 13 points higher than 7D.

Canon 5D MII vs Canon 7D Comparison of Available Lenses

Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Canon 7D has an advantage over Canon 5D MII There are 333 lenses for Canon 7D's Canon EF/EF-S mount, on the other hand there are only 257 lenses for Canon 5D MII's Canon EF lens mount.

Another important factor is the availability of image stabilization. None of these bodies have sensor based image stabilization so you have to buy lenses with Optical stabilization feature. Currently there are 77 lenses for Canon EF mount and 113 lenses for Canon EF/EF-S mount with IS.

Now let's compare some sample lenses from each mount with typical Focal ranges for Canon 5D MII and Canon 7D to see how these lenses compares:

What types of Photography are Canon 5D MII and Canon 7D Good for?

In this section, we rank and compare Canon 5D MII and Canon 7D for five different photography types in order to make your decision process easier in case you are specifically interested in one or more of these areas.

Canon 5D MII vs Canon 7D: OUR DECISION

You may have already made your decision about which camera suits better for your needs and your budget so far but in case you wonder how we rated Canon 5D MII and Canon 7D, below you can find their scores in five different aspects.
